Hi,
Since I love this mod and have been using it (with the version number bumped) on 2.1 with no issues I have uploaded a port of it for 2.1.

I figured it would be good to let you know and to post it here so those looking for a bumped version can find it easier.
Hopefully that's okay! thanks for the great mod :)
